Steganography is one of the cryptography techniques where secret information can be hidden through multimedia files such as images and videos. offer a way exchanging encrypted in an untypical mechanism communicating parties only interpret message. The literature has shown great interest least significant bit (LSB) technique which aims at embedding message bits into most insignificant image pixe...

Steganography is the science of hiding a message signal in a host signal, without any perceptual distortion of the host signal. Using steganography, information can be hidden in the carrier items such as images, videos, sounds files, text files, while performing data transmission. In image steganography field, it is a major concern of the researchers how to improve the capacity of hidden data i...

Today’s internet applications require data to be transmitted in a secure manner. Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the solution for this problem is Steganography. That has to do with secure data transmission between a sender and a receiver; implementing Steganography is the best way. Steganography...

Steganography has proven to be one of the practical ways of securing data. It is a new kind of secret communication used mainly to hide secret data inside other innocent digital mediums. Most of existing steganographic techniques use digital multimedia files as cover mediums to hide secret data. Audio files and signals make appropriate mediums for steganography due to the high data transmission...

In today’s world, there are a number of cryptographic and steganography techniques used in order to have secured data transfer between a sender and a receiver. In this paper a new hybrid approach that integrates the merits of cryptography and audio steganography is presented. First, the original message is encrypted using chaotic neural network and the resultant cipher text is embedded into a c...

Today, internet is widely used to transfer various secret data in all over the world. During transmission secret data, unauthorized viewers can monitor it. Steganography is mainly used to protect secret data from unauthorized viewers over communication channel. Steganography means the covered or hidden writing. There exits many steganography model such as image, audio, video or text. Among them...

It is well known that encryption provides secure channels for communicating entities. However, due to lack of covertness on these channels, an eavesdropper can identify encrypted streams through statistical tests and capture them for further cryptanalysis. Hence, the communicating entities can use steganography to achieve covertness. In this paper we propose a new form of multimedia steganograp...

Nowadays, information is rapidly available through the Internet. Companies have the ability to communicate with a worldwide audience through the World Wide Web. So Information hiding techniques are received increasing attention due to: the availability of multimedia and digital form objects. And the need to present solutions to criminal copying and copyright problems. In this paper, a new encry...

Shifali Singla Abstract— Image Steganography is the art of hiding message into a cover image. This paper presents a novel technique for image steganography based on DWT, where DWT is used to transform original image (cover image) from spatial domain to frequency domain. This paper reviews about the art of writing hidden messages in such a way that no one apart from intended destination knows th...
